That pink, blue, white, or any other coloured puck in the urinal that is supposed to cover up the smell of a few thousand pisses. Usually ineffective. "Newfie" is short for Newfoundlander, person that hails from a province known for its' screech, rocks and seasonal employment.
I was at the bar and had to drive home, so I took a bite out of the Newfie Breath Mint to disguise my screech breath.
